Answer:
(a) Ethanol can be converted to ethene by dehydration of ethanol in the presence of concentrated sulphuric acid at 170 °C temperature. The reaction is named as dehydration reaction. (b) Propanol can be converted to propanoic acid by oxidation in the presence of alkaline potassium permanganate and heat
Explanation:
Ethanol can be dehydrated to give ethene by heating it with an excess of concentrated sulphuric acid at about 170°C. Concentrated phosphoric(V) acid, H3PO4, can be used instead. The acids aren't written into the equation because they serve as catalysts.

Propanol is converted into propanoic acid by an oxidation reaction, where catalysts such as potassium dichromate and potassium permanganate are used.
